ELECTRIC LOCK.

C PECIFIGATION forming part of Letters Patent N 0. 657,853, dated September 11, 1900.

Application filed January 13 1900. berial No. 1,298. (No model.)

To all whom it may concern.-

Be it known that I, HENRY GUY (JARLE'roN, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Electric Locks, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in electric locks.

One of the objects of the invention is to provide a simple, cheap, and efficient lock in which the withdrawing mechanism for the movableengaging part, such as the bolt or keeper, all be normally inoperative to move said part, but in which a controller is provided which may be caused to engage the movable engaging part, thereby rendering the withdrawing mechanism operative.

Another object of the invention is to produce an electric lock in which the withdrawing mechanism for the movable engaging part, such as the bolt or keeper, is normally inoperative to move said part and in which a controller is provided to render the withdrawing mechanism operative, the controller being actuated by electrical means, the circuit for which is preferably, though not necessarily, controlled by devices actuated from the withdrawing mechanism.

With these and other objects in view the invention consists in certain construction and in certain parts, improvements, and combinations, as will be hereinafter described, and more fully pointed out in the claims hereunto appended.

In the accompanying'drawings, which form part of this specification, and in which like characters of reference indicate the same parts, Figure 1 is a view in side elevation of the lock and easing, one of the sides of the casing being removed to show the operative parts of the lock. Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a horizontal sectional view taken on the line 3 3 of Fig. 1 looking in the direction of the arrow in said figure.

Referring to the drawings, which show one concrete embodiment of the invention, 1 indicates a lock-casing in which the operative parts of the lock are contained. In the lock the movable engaging part consists of a sliding bolt 2, the said bolt being designed to engage a stationary keeper which is not shown. It is obvious, however, that the keeper might be made the movable part, if desired. The movable bolt 2 passes, as is usual, through an openingin the front side of the casing and is provided with a stem 3, which works through an opening in a supporting-bracket 4. The bolt is provided with a rim or projection 5 and is held forward to its duty by a spring 6, which surrounds the stem. In the lock shown two sets of withdrawing mechanism are provided, though one set may be dispensed with in some cases. These sets of withdrawing mechanisms may be Widely varied in form and construction. Preferably, however, the operative devices for them Will lie on opposite sides of the look. In the lock shown one of the withdrawing mechanisms includes a slide 7, said slide being supported by the bracket 4, before described, and also by another similar bracket 8. The slide 7 is provided with any suitable means for withdrawing the bolt, and the withdrawing mechanism with suitable actuating devices. In the construction shown the slide carries a pin 9, which engages the rim or projection 5, before referred to, and while the actuating device for the slide may be widely varied in construction in the lock shown it includes a rotating cam 10, which engages a projection 11, carried by the slide, said cam being secured to a squared knob-shaft 12, which is operated by a knob 12.

It will be noticed that all the parts of the withdrawing mechanism just described are normally in engagement, so that when the knob is operated the bolt will be withdrawn.

In addition to the withdrawing mechanism before described there is provided a second withdrawing mechanism, which is independent of the one hereinbefore referred to. While this second withdrawing mechanism may be Widely varied in form and construction, in the lock shown it includes a slide 13,

which is suitably supported in the brackets 4 and 8. This slide 13, in the construction shown, is not provided with means for engaging the bolt or other movable engaging part, but its movement is made effective to operate said part by means of a controller. This controller may be also varied in construction, location, and arrangement. In the construction shown it consists of a part 14, preferably constructed in the form of a hook, and it will preferably be arranged to move the slide 13, before described. While this may be accomplished in various ways, the controller will preferably be pivoted to the slide, the pivotal point thereof being indicated at 15.

-While the controller may be operated in any suitable manner, it will preferably be electrically operated. Various electrical devices may be used to operate the controller; but in the construction shown there is provided a magnet, said magnet being supported by a bracket 16, located in the lock-casing. While any suitable form of magnet may be used to effect the movement of the controller and While the magnet may operate directly upon the controller or through intermediate devices, in the construction shown the magnet is of the class known as a club-foot magnet-that is to say, it is provided with a single coil 17, which surrounds one of the poles 18 of the magnet, said pole being of the ordinary description and the other pole consisting of a bent bracket-like part 19, which is secured to the pole 18. In the construction shown the controller is arranged so as to form the armature for the said magnet,though this arrangement is not a necessary one. When, therefore, the magnet is energized, the controller is turned on its pivot,and its hooked end is caused to engage the rim or projection 5, before referred to. The magnet may be located at any suitable point in the path of the controller. Preferably, however, it will be arranged close to the pivotal point of the controller when the parts of the lock are in their normal position-that is, when the parts are in the position shown in Fig. 1. By thus arranging the magnet close to the pivotal point of its controller-armature the poles of the magnet can be brought very close to the controller-armature. The attractive force of the magnet is thus exercised to the greatest possible advantage, and at the same time a slight movement of are near the pivotal point of the armature produces a Very considerable movement at the operating end of the controller.

By referring to Fig. 1 it will be seen that when the magnet is energized poles 18 19 of the magnet will draw the armature against them, and although the movement at the points where the poles operate in the first instance is a very slight movement, yet the movement of the hooked or engaging end of the controlleris of considerable extent. Furthermore, as slide 13 is moved through its op erating devices, to be hereinafter described, the controller will be held against the poles of the magnet, so that engagement of the hooked end of the controller with the projection of the sliding bolt will be insured.

Any suitable actuating device may be provided for the slide 13. Preferably, however, the said actuating device will include a rotating cam 20, said cam being mounted on a squared knob-shaft 21, the knob 21 of which lies on the opposite side of the casing from knob 12, before described. The rotating cam 20 is arranged to engage a projection 22, secured to the slide 13. The actuating device described operates to move the slide in one direction only, and in order to move it in the other direction there is provided a spring 23, which is secured to a pin 24:, carried by a slide, the other end of the spring being secured to the lock-casing 15 by a screw or in any other suitable manner.

Any suitable circuit or circuits may be provided for energizing the magnet before described. Preferably, however, the circuit will be open at two points, and preferably, also, it will be closed at one point by the movement of the withdrawing mechanism. In the construction shown a battery 26, located at any suitable point, is provided, said battery being connected with the magnet by a wire 27. Extending from the otheside of the battery is a wire 28, which leads to a circuit-closer, shown as an ordinary push-button 29, which may be located at any suitable point. From the push-button is led a wire 30. While a circuit open at one point might be used and the wire led directly from the circuit-closer to the magnet, in the construction shown, as has been stated, the circuit is open at two points and is closed at one of the points by the movement of the withdrawing mechanism. Various devices variously located may be employed to eifect the closing of this circuit by the movement of the withdrawing mechanism; but these devices will preferably be located within the look. In the construction shown, which represents a simple and effective form of circuit-closing device, the wire 30 leads to the rotating cam 20, said cam being provided with a recess 31. A suitably-mounted terminal-such, for instance, as a spring 32-is located within the casing, the end of said spring lying in the recess 31 and out of contact with the cam 20. From the spring 32 a wire 33 is led around the magnet. With the circuits described it will be seen that when the push-button 29 is operated and the knob 21" is turned the cam 20 will strike against the spring 32, closing the circuit through the magnet, causing it to attract the controller-armature. The movement of the controller-armature causes its hooked end to engage with the projection 5, before described, and the bolt will be withdrawn. If, however, the knob 21 is operated without operating the circuit-closer 29, the slide 13 will be operated, but there will be no movement of the controller-armature about its pivot, and the bolt therefore will not be withdrawn.

By providing a circuit open at two points a conservation of'battery energy is effected, since the battery is not thrown into operation until the instant the lock is to be operated. This point is of importance in connection with the open-circuit batteries which are ordinarily used in devices of this class, as such batteries run down very quickly. It is not to be understood, however, that the main features of the invention are limited to the use of open-circuit batteries, as batteries employing a closed circuit might be used therewith with slight modifications of construction.

The ordinary torsional springs will be used in connection with the knob-shafts, one of said springs being shown at 34 and operating upon knob-shaft 21. Suitable stops 35 36 are also provided to limit the movement of the cams 20 and 10.

The constructions by which the various features of the invention may be carried into efiect may be varied within wide limits. The invention therefore is not to be limited to the specific constructions herein described.
